Tank ON - Modern Defender

Tank ON is a non-stop action! It’s a modern version of the castle defender games including lots of RPG elements. Your mission is to shoot, smash and finally to destroy all the unfriendly forces trying to invade your base.
Control the turret which moves in front of your base, and fires machine gun or heavy cannon at the enemies. The turret is protected by a force field, so it can "catch" the enemy shells, preventing the damage to the base.
Use special weapons:
• The Orbital Ion Cannon capable of destroying multiple targets at once
• The impact of electromagnetic waves that paralyzes enemy vehicles
• The force field that protects the entire base and
• The Nuclear bomb which blast covers the whole battlefield.
For every enemy destroyed you get silver coins, and gold coins for the completing of missions, and protecting your base.
Spend the coins between missions to upgrade weapons and protection of the base, and to improve special weapons as well!
